There are t queries. In each query, you are given two positive integers a and b . Please print a line consists of four positive integers c,d,e,f satisfying the following constraints: cdef=abfrac{c}{d} - frac{e}{f} = frac{a}{b}dcfe=ba d < b and f < b 1≤c,e≤4×10121 le c,e le 4 times 10^{12}1≤c,e≤4×1012 If there are multiple solutions, you can print anyone. If there are no solution, please print "-1 -1 -1 -1" in this line.
